Figure 24. Example 2: Analog inputs with setpoints update on True and False
Detection on an analog input, timer output updates
Update Mode: Update on True and False
Criteria Used: Inside window
Figure 25 shows how a setpoint can be used to update a timer output. Channel 3 is an analog input channel. A
setpoint is applied using update on True and False, with a criteria of inside-the-window, where the signal value
is inside the window when simultaneously less than Limit A but greater than Limit B.
Whenever the channel 15 analog input voltage is inside the setpoint window (condition True), Timer0 is
updated with one value; and whenever the channel 15 analog input voltage is outside the setpoint window
(condition False) timer0 will be updated with a second output value.
